auto route and direction not always work

G’day Wongkasep,

It’s a bug — it only shows the directions when the map marker has a title. I’ll try to fix it sometime this week, but it’s a busy week so I can’t commit to that.

In the meantime, you can get the route working by adding title="Kuala Lumpur" to your shortcode.

cheers,
Ross

Hi Ross,

Thanks for the fast response. I have added title and description into shortcode, but the map still not stable. The route and directions not always shown.

Perhaps be a little more specific with your directions. It might be that Google Maps can’t tell where to search from. e.g. instead of just “Port Dickson”, try “Port Dickson, Negeri Sembilan, Malaysia”. Also set region="MY" to let Google Maps know what region to preference.

cheers,

Yes, I think the map need more specific definition. Unfortunately, it still doesn’t solve the problem after changing the locations more specific.
I use mozilla firefox when experiencing such phenomena. However, the map is more stable if it opened with Chrome.

I’m not seeing any problems with that shortcode pasted into a post, no other plugins, twentytwelve theme. Can you check for script errors in the browser, maybe send me a link to the page?

cheers,

Ok, I try to deactivate one of other less important plugin, and the map looks more stable, but still find a few “unshowed” directions. Sorry for not showing my url here, but I will send it to your email.

Is it because of the destination place also act as map center? So, the plugin sometime stopped after centering map, before creating route?

It’s likely a JavaScript error in something else on the page. The initial map render happens before the error, and a directions request is sent to Google Maps, then a JavaScript error happens and no other events are processed. At least, that’s my best guess without seeing the website. I’ll await your email — please send via the contact form if possible.

cheers,

Thanks Ross,

I have sent my url into contact form.

?Got that, and I reckon I can see what’s likely to be causing the problem. Because you have three different things loading the Google Maps API, you’re going to have problems! It even says so right in the Google Chrome console:
?

?Warning: you have included the Google Maps API multiple times on this page. This may cause unexpected errors.
?Warning: you have included the Google Maps API multiple times on this page. This may cause unexpected errors.

?Yes, twice, once for each of the second and third times the maps API is loaded.

To fix, probably the easiest way is to hook into the wp_print_scripts action and sniff the post content to see if it has a [flexible_map] shortcode. If it does, wp_dequeue_script() the other plugins’ Google Maps scripts, so that they don’t load. My plugin’s scripts only load if there’s a shortcode, so you don’t need to worry about the inverse case.

Are you able to do that yourself, or do you need a hand?

cheers,
Ross

Hi Ross,

I have read your suggestion carefully, but still have no idea what should I do. LOL

Yes, I need a help.. What should I do?
Sorry, I don’t know how to say Very Much Thanks in a good phrase.. ??

Wongkasep

I’ll have a look at it tomorrow, please tell me which other map plugins you are using.

cheers,
Ross

Other map plugins (active) : Ultimate Google Maps, Map List Pro, and JQMap Route Calc

Thanks in advance for the best support,

Wongkasep

G’day Wongkasep,

So, all of those plugins are “premium” (i.e. non-free), so I expect you sought support from them first, yes? Since they are breaking this plugin!

I’ve written a small plugin to knock off other plugins’ Google Maps API scripts in a generic way that hopefully will prevent conflicts. To test it, I had to write another plugin that played bad, because the few free Google Maps plugins I randomly picked to test against play good — I couldn’t get a conflict with another free plugin, so I had to confect one.

Download the file from this gist and install as a plugin, then activate. It’ll only remove other plugins’ Google Maps API scripts when there’s a Flexible Map shortcode on the page / post, or when you’ve explicitly enqueued the Flexible Map scripts yourself.

https://gist.github.com/webaware/3806a2dfdf2abcb61f64

Let me know how that goes, I’m hopeful it fixes your problem.

cheers,
Ross

Yes!! Perfect! I have installed the gist, then loading the page many times, all maps are running successfully with route and directions showed. I think it has no conflict with other map plugin again.

Thanks you so much Ross.. your plugin is free, but your support is more than premium! Excellent support! I have some report in this forum, and all problems are solved in a few hours! Excellent!

Best Regards,

Wongkasep

Excellent, another happy ending. I’ll have to add a troubleshooting section to the website and have a page for this one.

cheers,
Ross
